In reply to Simon:
How long will it be before someone thinks it's a good idea to used different coloured chalk on bits of crags and boulders where a number of routes / problems cross the same ground but use different hold sequences?
It will soon be just like climbing indoors!
I wonder how well most boulderers would cope when faced with a run out pitch on a mountain crag where route finding plays a bigger part than just technical ability.
Donkey ticks ? -- is that because those who employ them lack the basic imagination or intelligence to be able to remember a sequence or where a hold is to be found.
What would they do if faced with a similar problem in a position where a donkey tick is impossible to place.
Blind moves are exactly that -- you've got to solve the problem, not cheat. At least on boulders you've got an opportunity of weighing the moves from various angles before you start -- so why do people feel the need to mark them out first?
Methinks some people need to get a life!
